Hey Doc, I highly recomend calling the vendor directly regarding emissions...... As mild as you are planning I doubt any problems, but that is a PITA job to do in the car if you find it won't pass. Make a 5 min call and be sure

I would recommend the roller rockers. With the higher rate springs and the higher lift cams, they should make the valve train last longer as well as make a couple of horsepower.

Really? I wouldn't have guessed that! What about the rest of the cars they came packaged in?

Yup, true story.

So far every fastener I touched on my C5 Z06 except the aftermarket blower tensioner reinforcement is metric. I assume the same is true for the other LS cars as well (camaro, caddy cts, gto, etc)

by the time the LS came out gm had gone full metric. it was the LTs that had a mix of metric/SAE

The roller rockers aren't really necessary for a 228* cam, the stock LS rocker arms are pretty good--they're roller, but not roller tip. They're also really easy to change out later if you decide that you need to!

Make sure you get an upgraded billet double-roller timing set, and a good oil pump. I just went with an SLR pump (IIRC).

that is incorrect

all the fasteners on a LTx are metric headed. Some still have SAE threads but have been metric headed since the 80's

Well if that doesn't make perfect sense, I don't know what does...

As far as what i carry in terms of tools whenever i hit the road, i always use Metrinch anyways: http://www.metrinch.com/

They fit both standard and metric nuts/bolts and they're way less likely to round off the head of something. Worth every penny!
